Leviticus 4:8-10

New Century Version

⁸ He must remove all the fat from the bull of the sin offering—the fat on and around the inner organs, ⁹ both kidneys with the fat that is on them near the lower back muscle, and the best part of the liver which he will remove with the kidneys. ¹⁰ (He must do this in the same way the fat is removed from the bull of the fellowship offering.) Then the priest must burn the animal parts on the altar of burnt offering.
